thermostat with Oled display, control from the Supla App and buttons for local control.

Image

channel 0 = automatic / manual thermostat
channel 1 = manual relay on / off
channel 2 = to the left the temperature decreases by 0.5º the right increases by 0.5º
channel 3 = temperature DS18B20
channel 4 = thermostat temperature

temperature and hysterysis are adjusted in wificonfig
temperature in x10 format (22º is written 220 in the configuration)
It can be changed from the app in 0.5º steps and will be stored
hysterisis in x10 format (+/- 1 is written 10 in the configuration)

Supla App

Image

local control:
thermostat toggle Auto/Man------Enter WifiConfig holding for 10 seconds.
relay toggle on/off.
decrease thermostat temperature 0.5ºC.
increase thermostat temperature 0.5ºC

the screen automatically dims after 15 seconds and the first press on one of the buttons makes it bright again.

if any button is pressed while the screen is dimmed, it will glow and the following presses will acruate according to the button pressed.

After 15 seconds without pressing any button the screen dims.

After changing the temperature of the thermostat, the display reverses for a moment indicating that the new value has been stored.

relay off when switching from auto to manual mode to allow schedule.

in case of a connection error with Supla cloud it display "Exx" instead of the supla logo, with xx being the error number.

Unfortunately I don't have one. Same 0.96 Inch OLED. But I have to get bigger because my eyesight is not the same ...

Congratulations. That's what I expected from you, oled display, now what if you implement a webserver so we can use it even when the clowd is not recheable. :mrgreen:

The thermostat works great.
Even without wifi.

Image

channel 0 = automatic / manual thermostat
channel 1 = manual relay on / off
channel 2 = to the left the temperature decreases by 0.5º the right increases by 0.5º
channel 3 = temperature DS18B20
channel 4 = thermostat temperature

temperature and hysterysis are adjusted in wificonfig
temperature in x10 format (22º is written 220 in the configuration)
It can be changed from the app in 0.5º steps and will be stored
hysterisis in x10 format (+/- 1 is written 10 in the configuration)

Supla App

Image

local control:
thermostat toggle Auto/Man------Enter WifiConfig holding for 10 seconds.
relay toggle on/off.
decrease thermostat temperature 0.5ºC.
increase thermostat temperature 0.5ºC

the screen automatically dims after 15 seconds and the first press on one of the buttons makes it bright again.

if any button is pressed while the screen is dimmed, it will glow and the following presses will acruate according to the button pressed.

After 15 seconds without pressing any button the screen dims.

After changing the temperature of the thermostat, the display reverses for a moment indicating that the new value has been stored.

relay off when switching from auto to manual mode to allow schedule.

in case of a connection error with Supla cloud it display "Exx" instead of the supla logo, with xx being the error number.
